I'm running Android version 4.7.1. A friend created a PDF book and loaded an index for it onto the iGigBook server (I've confirmed that it is active). I first synced my Book View, then loaded the book into My Scores and selected his index under Link to Index. The book disappeared from My Scores (as expected) but I can't find the index in Book View, and none of his titles show up in Song Search.

An aside: when my tablet is connected to my Windows 10 computer, it shows up like any other drive and I can see iGigBook's contents. After my attempts to find the book in the iGigBook app, I notice that the name of the book has been changed to for some reason.

Looking into this further it seems you created to custom book entries but did not create any song entries for either of the custom books. Those index entries will not show up in your Book List view unless they have song entries associated with them.
